Thanks Samuel for your reply. We do have our own build of Qt, but I really would avoid to change them, it would be very difficult for us to keep our changes in sync with the new Qt distributions. >> but the bindTexture returns a valid texture id (> 0) and the >> glGetError() returns 0 (no error). >> How do I know the binding has failed from my code? > Yeah, glGetError() won't return an error since it clears the error state > when it's called from within bindTexture(). > > Btw, which OS and Qt version are you using? I'm using Qt 4.7.3 on Windows, Linux and Mac. I double checked the bindTexture source code on Qt 4.8 and there does not seem to be a different error handling than in 4.7 version :( -- Calogero Mauceri Software Engineer Applied Coherent Technology Corporation (ACT) www.actgate.com _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
